Silicon metal powder is also called industrial silicon powder. It is silver gray or dark gray powder with metallic luster. Of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called 'industrial glutamate', which is an essential basic raw material in hi-tech industry.

Perfect Crystallization, good size of Flake, High density, Low content of mica , High luminance, and Excellent physical features, such as the Thermostability, Electric and Thermal conductivity, Self-lubricity and Superior Chemical stability.

Manganese has numerous applications which impact on our daily lives as consumers, whether it be of objects made of steel, of portable batteries, or of aluminum beverage cans. In each case manganese plays a vital role in improving the properties of the alloys and compounds involved in each specific application.

Manganese has played a key role in the development of various steelmaking processes and its continuing importance is indicated by the fact that about 90% of all manganese consumed annually goes into steel as an alloying element.

The calcium iron cored wire functions as the deoxidizer and the desulfurizer in the process of steel-smelting production, mainly applied to cold heading steel, pipe line steel, and other low-silicon steel types. Its core powder material is metal calcium and pure iron powder, and in order to prevent oxidation of metal calcium in the air, our Chinese principal has been the first enterprise to perform blending of materials and processing of this product under vacuum condition, in which the affinity of calcium with oxygen and sulfur elements is considerably huge in both cases, able for de-oxidation and de-sulfurization of molten steel. Its deoxidized outcome – CaO is also mingled and combined with Al2O3 system in the liquid steel to generate 7Al2O3-12CaO sinter of low-melting point, thus to avoid the effect of nozzle blockage arising from condensation of casting nozzle mingled with Al2O3 system, so as to ensure a smooth continuous casting production. The desulfurized outcome floats upwards very easily to be removed, so as to enhance the plasticity and tenacity of steel.

Size: 10-100mm &10-50mm Packing: packing with poly bags filled argon gas in then sealed in steel drum, In the process of metal smelting, Calcium Aluminium alloy can be used as intermediate medium alloy.

Boron Carbide (B4C) is one of the hardest man-made materials. Its hardness with Mohs hardness 9.36 and microscopic hardness 5400 to 6300kgmm²is only exceeded by cubic boron nitrides and diamond. Its density is 2.52gcm³ and melting point is 2450°C. Boron Carbide powders are characterized by excellent properties, such as high boron content, high alkali and acid resistance, outstanding heat resistance, high grinding efficiency, and no magnetism. It is the ideal substitutes for diamond.
